As a rough test it’s definitely not flashy, but it’s my first successful attempt to drive a Tesla coil with an external oscillator (HAM radio), and the first successful test with a grid bias board I had designed last month. See, most vacuum tube Tesla coils are usually armstrong oscillators that resonate against their own …

So, if all non-conservative electrical systems operate based on parametric variation (of permittivity/permeability), then applying a static DC potential and/or current to a simple Tesla Extra coil should result in small EMP-like impulses when the coil is energized with conventional standard RF near the resonant frequency. It’s crazy the things we think up when we’re …
Doing some initial low-power tests with a cheap ‘100 watt’ linear HF amplifier for Tesla Coil experiments. Oddly, this amp seems to work best without a tuner. Perhaps some quirk with impedance, I haven’t tracked it down yet. Powering a Tesla Coil Extra it lights florescent bulbs nicely at a few feet away, though the …
For those unfamiliar, I do a lot of engineering+science project updates on Minds and Bitchute (formerly Twitter). Hopefully there will be something that piques your interest.😉
Following experiments with a homemade plastic injection molding machine, the zeitgeist led me to construct and experiment with an aluminum metalcasting foundry. Inspiration: https://www.instructables.com/id/Propane-Tank-Aluminium-Smelter-No-Weld/ Summary:Â Â I had great initial success following the blog as a guide for building a casting foundry, but eventually I ran into far too many issues with the burner. At first, …
